Chelsea's midfield double act of Nemanja Matic and Cesc Fabregas have been outstanding and their partnership has been key in their title success.

Matic's dominance as a midfield anchorman allied to Fabregas's vision and range of passing give Chelsea a perfect blend.

Fabregas's influence should have received recognition with a place in the PFA Team of the Year alongside Matic. Fabregas has been outstanding and is surely one of the the stars of the season.

But Chelsea boss Mourinho wants to strengthen his midfield and up front even though Diego Costa has been one of the best strikers in the Premier League.

But, rather like in midfield, Chelsea want more depth and options to choose from next season as they look to retain their title and also try to go for success on more fronts, particularly in Europe.

Mourinho will look to reshuffle his squad this season and there will be some big new arrivals but it will be interesting as Chelsea also look to some of their outstanding home grown English youngsters.

Chelsea midfielder Ruben Loftus-Cheek, 19, has been on the bench a few occasions this season and Mourinho has singled him out as one for the future.

Similarly, Chelsea teenage striker Dominic Solanke also looks destined for big things and, while Mourinho may add another striker, the 17-year-old has also been promised a chance next season.

Mourinho insists Solanke is staying at Chelsea next season rather than being farmed out on loan and Chelsea may just look to Loftus-Cheek rather than make a huge bid for Juventus midfielder Paul Pogba,

Mourinho said: "For him (Solanke) to go on loan for a Championship team, or to another team in England or Europe, would be a big mistake.

"Staying at Chelsea, training with the first-team, having pre-season with the first-team, some period as cover to the main strikers, playing every week at U21s and U18s... probably, he would never need to go out on loan, and just go step by step here. At 18, in a couple of years, first-team player.

"I think we are doing the right thing. But when a player is like Loftus-Cheek or Solanke, where we know for sure they have the potential to play for Chelsea one day, when they are so young it's better for them to stay at Chelsea and develop.

"Ruben is a great example. He was never on loan. He was working and waiting, and now he knows that next season he's a first-team player."
